Iiseramics ezinamaqhekezaliqela lezinto ze-ceramic ezixutywe kakhulu ezinokuthi zithathe uhlobo lwezakhiwo ezahlukeneyo, kubandakanywa i-foam, i-honeycombs, iintonga ezidibeneyo, iifayili, i-hollow spheres, okanye i-interconnecting rods kunye ne-fibers.

Iiseramics ezinamaqhekezazihlelwa njengazo zinepesenteji ephezulu ye-porosity, phakathi kwe-20% kunye ne-95%. Ezi mathiriyeli zenziwe ngamanqanaba amabini ubuncinci, njengesigaba esiqinileyo seceramic kunye nesigaba seporous esizaliswe yigesi. Ngenxa yokuba nokwenzeka kokutshintshiselana ngerhasi nokusingqongileyo ngokusebenzisa imijelo yepore, isiqulatho segesi kwezi pores sihlala siqhelana nokusingqongileyo. Iipore ezivaliweyo zinokubamba ukubunjwa kwegesi ezimeleyo kwi-atmosphere engqongileyo. Nayiphi na i-porosity yomzimba we-ceramic ingahlelwa kwiindidi ezininzi, kubandakanywa ukuvula (ifumaneka ngaphandle) i-porosity kunye ne-porosity evaliweyo. Iipore ezivulekileyo ezivulekileyo kunye nemijelo evulekileyo ye-pore zimbini ezincinci ze-porosity evulekileyo. I-porosity evuleke ngakumbi ingafuneka ukuze ikwazi ukungena, ngokuchaseneyo ne-porosity evaliweyo, okanye izihluzi okanye ii-membrane, ezifana nezithinteli ze-thermal, zinokufunwa. Ubukho be-porosity buxhomekeke kwisicelo esithile.

Iipropathi zekeramics ezinomqolo zinokuchatshazelwa kakhulu lutshintsho kwi-porosity evulekileyo nevaliweyo, ukuhanjiswa kobungakanani bepore, kunye nokumila kwepore. Iimpawu zesakhiwo se-Porous Ceramics, njengeqondo le-porosity, ubungakanani bepore, kunye nefom, zimisela iimpawu zabo zomatshini.
